Need to hire individual to implement changes to my website

I have an existing subscription based website for online motorcycle instructional video clips and have had it up an running since feb08. We need someone to implement an affiliate program for my members, where they get $5 off for each new member they refer to us. Also I would like a bulletin board forum for exixsting members, and (forgive me for my choice of words), but a instructional video filtration of some sort. I have currently over 24 instructional clips and you can join today an get access to all, well I would like to only give access to two of there choice each mnonth to keep them on as members. Also is there anyway to protect my clips, an make them accessable to my members so they can downlaod them to there ipod, but not share........please contact me via email richlafferty@hotmail.com.I would like this set up within a week, and can pay you via paypal. Thanks, Rich
